They are the same from the viewpoint that the purpose of alt text and audio description is to convey visual information in a way that makes it possible for someone who cannot perceive that information visually.

However, they are very different when it comes to implementation. Alt text is just text--typically used to describe the important information provided by a static image. Audio description is a spoken audio track where someone describes the important visuals of a video.

Thanks!
